Patients don't like getting needles, nor do clinicians like having to keep protein-based vaccines cold at all times. A new polymer wafer – which dissolves when placed under the tongue – could address both issues.

When a child receives a replacement heart valve, the device doesn't grow along with them. This means it will have to be surgically replaced, multiple times. Such may not be the case, however, with a new valve that's currently in development.

A number of hearing aids are now able to amplify one person's voice while filtering out distracting background voices. Well, it turns out that female tree frogs are able to perform a similar task, in order to hear the mating calls of males.

Astronomers have detected a strange signal coming from neutron stars that could be a new elementary particle. An unexplained excess of X-rays hints at axions, hypothetical “ghost” particles that could solve several long-standing physics puzzles.

Researchers have for the first time managed to use electricity to switch on magnetism in a material that’s normally non-magnetic. This could be a step towards making electronic components out of common materials that might not otherwise be suitable.

Once discarded, spongy polyurethane foam typically just ends up in landfills, where it takes up a lot of space. Thanks to a newly-developed process, however, it could soon be recycled into higher-quality rubbers and hard plastics.

The final results of a Phase 2b human trial into the efficacy of a new tuberculosis (TB) vaccine have been published, indicating safe long-term protection from the devastating disease in around half of the subjects vaccinated.

There is a lot to learn about Alzheimer’s and how it can be better treated. Scientists now have an inventive new tool with which to look into such matters, in the form of a transparent skull that allows them to peer into heads of mice.

​When he was an assistant professor at Princeton University, Michael McAlpine led the development of a 3D-printed bionic ear. Now an associate professor at the University of Minnesota, he has gone on to 3D-print a rudimentary bionic eye.

Researchers at the University of Minnesota have designed a silicone device, covered in 3D-printed neuronal stem cells, that can be implanted into a spinal injury. There it grows new connections between remaining nerves to let patients regain some motor control.

Various research institutes have already developed skin-applied electronics, that are simply adhered to the user's body. Researchers at the University of Minnesota, however, have taken a different approach. They've developed a method of 3D-printing custom electronics directly onto the skin.

There may be an unexpected upside to being relatively forgetful – you might be able to enjoy things for longer. A new study has found that people with a higher-capacity memory tend to get bored faster, due to the fact that they remember experiences in more detail and feel more satiated by them.
